Product Features and Design
The expansion joint features a spherical, molded single-arch body constructed from high-grade synthetic elastomers and reinforced with multiple layers of high-strength tire cord fabric. The arch design provides a long radius that reduces turbulence and minimizes sediment buildup, ensuring smooth flow and system efficiency.
The defining feature of this product is its zinc electroplated floating steel flanges. Unlike fixed flanges, these are not rigidly bonded to the rubber body, allowing them to rotate freely. This design simplifies installation by enabling easy alignment with mating pipe flanges, eliminating the need for complex adjustments or additional gaskets.
Key Benefits and Performance
Installing an ANSI Floating Flange Rubber Expansion Joint delivers several critical advantages to a piping system:
Multidirectional Movement Absorption: The joint effectively compensates for axial compression and elongation, lateral deflection, and angular displacement. This flexibility protects pumps, compressors, and other connected equipment from stress and mechanical failure.
Vibration and Noise Reduction: The elastomeric body dampens vibrations generated by rotating machinery and significantly reduces noise transmission through the pipe wall, extending system life and improving working conditions.
Corrosion and Abrasion Resistance: Rubber compounds offer superior resistance to chemical erosion, abrasion, and corrosion compared to thin-walled metal joints. The thick rubber wall provides a durable barrier against abrasive slurries and corrosive fluids.
Simplified Installation and Maintenance: The integrated vulcanized rubber flanges and the freely rotating steel flanges eliminate the need for separate gaskets and sealants. This reduces installation time and eliminates ongoing gasket maintenance checks.
Materials and Construction
The expansion joint is crafted from a choice of high-performance materials to suit specific media and temperature requirements. Common elastomers include EPDM, NBR, and Neoprene, each providing compatibility with water, seawater, hot water, oil, weak acids, and alkalis.
The joint body is reinforced with high-strength synthetic cord for pressure retention and includes high-tensile steel reinforcement for added durability. Retaining rings are typically hot-dip galvanized for superior corrosion protection. The standard flange drilling follows ANSI B16.5 Class 150 specifications, with other standards like DIN, JIS, and AS available upon request.
